Abstract
The invention relates to a steering mechanism of a tracked miniature rice and wheat combine harvester. The steering mechanism comprises a gearbox, a pair of clutches is arranged on the left side and the right side of the gearbox, the clutches can control connection and disconnection of power of tracks on the same side, and each clutch comprises a shift fork gear and a return spring. The steering mechanism is characterized by further comprising a pair of brakes, when the shift fork gears are disconnected from power, the brakes enable the shift fork gears to be in the braking state, and when the shift fork gears are connected with power, the brakes enable the shift fork gears to be in the non-braking state. The steering mechanism is simple and compact in structure, a differential needs not to be disposed to realize steering, production cost is saved greatly, the steering mechanism is small in turning radius, flexible and convenient for steering and laborsaving and timesaving, and operation efficiency is increased by more than 5 times.
Description
Technical field
The present invention relates to a kind of crawler type miniature rice-wheat combine harvester, especially a kind of steering mechanism of crawler type miniature rice-wheat combine harvester.
Background technology
The endless-track type rice-wheat combine-harvester of prior art, its steering principle is, by gearbox left and right, clutch is set respectively, which side is the power break-make of Clutch Control homonymy crawler belt, turn to, and throws off the power of homonymy.A certain side is thrown off after power, and the transmission mechanism of this side is in free state.When a dynamic side drive body advances or retreats, drive opposite side is advanced simultaneously or retreated.This structure is suitable for the large field operation of large type, is unsuitable for little type.Adopt the miniature rice-wheat combine harvester of this structure, in the time of turning to, operator only has and firmly pulls handrail and could realize, and its operation is effort very.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of steering mechanism of crawler type miniature rice-wheat combine harvester, and its turning radius is little, operates easy and convenient.
The present invention adopts following technical scheme: comprise gearbox, the described gearbox left and right sides is provided with a pair of clutch, clutch can be controlled the break-make of homonymy crawler belt power, clutch comprises shift fork gear, return spring, also comprise a pair of brake, when described shift fork is out of gear power, brake makes shift fork gear become on-position, during described shift fork gear couplings power, brake makes shift fork gear become non-on-position.Its principle is: when the straight line moving of chassis, under the effect of return spring, two of left and right clutch is respectively in bonding state, and the crawler belt of both sides all connects power, and now two brakes are in disengaged condition.In the time of need to turning to a certain side, pull the steering tiller of homonymy, shift fork drives the shift fork power that is out of gear, and brake makes shift fork gear become on-position simultaneously, and the joining transmission mechanism of this side and crawler belt is in on-position.Thus, the phenomenon of having avoided a dynamic side to drive unpowered (free state) side to advance simultaneously or retreat.Adopt body of the present invention, can minor-circle turn, body can circle around the one-sided crawler belt central point that lands.
A kind of improvement is that described brake comprises the spline housing being installed between shift fork gear and return spring, the multiple-piece friction brake wafer that pressing plate is installed between spline housing and housing and matches.This simple and compact for structure, stable and reliable for performance.
Tool of the present invention has the following advantages: 1, simple and compact for structure, production cost is low.Can adopt standard gearbox, without special gear box, also without configuration differential mechanism, realize and turning to, greatly save production cost.2, radius of turn is little, and clearance circle is the centre distance of two crawler belts, and the radius of turn that has a kind of embodiment is 800mm.3, turn to flexibly and easily, laborsaving saving time, operating efficiency improves more than 5 times.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present invention.
Embodiment
As shown in Figure 1, an embodiment of the present invention comprises gearbox 11, described gearbox 11 left and right sides are provided with a pair of clutch 12, clutch 12 can be controlled the break-make of homonymy crawler belt power, and clutch 12 comprises shift fork gear 1, return spring 2, also comprises a pair of brake 3, when described shift fork gear 1 is thrown off power, brake 3 makes 1 one-tenth on-position of shift fork gear, and when described shift fork gear 1 connects power, brake 3 makes 1 one-tenth non-on-position of shift fork gear.Its principle is: when the straight line moving of chassis, under the effect of return spring 2, two of left and right clutch 12 is respectively in bonding state, and the crawler belt of both sides all connects power, and now two brakes 3 are in disengaged condition.In the time of need to turning to a certain side, pull the steering tiller of homonymy, shift fork drives shift fork gear 1 to throw off power, and brake 3 makes 1 one-tenth on-position of shift fork gear simultaneously, and the joining transmission mechanism of this side and crawler belt is in on-position.Thus, the phenomenon of having avoided a dynamic side to drive unpowered (free state) side to advance simultaneously or retreat.Adopt body of the present invention, can minor-circle turn, body can circle around the one-sided crawler belt central point that lands.
A kind of improvement is that described brake 3 comprises the spline housing 4 being installed between shift fork gear 1 and return spring 2, the multiple-piece friction brake wafer 7 that pressing plate 6 is installed between spline housing 4 and housing 5 and matches.This simple and compact for structure, stable and reliable for performance.
The present invention is not limited to the concrete structure of above-described embodiment, within the equivalent transformation of other homogeneous structure all falls into protection scope of the present invention.
Claims (2)
